The perspective of long term maintainability being more important is completely understandable. Also, your comments on the other alternatives are well-taken. Thank you very much for your input. Then, I will update my patch based on the full match, also reflecting your review comments. In the meantime, I'd like to confirm one remaining option that we haven't yet discussed, just to consider all possibilities. If the concern is primarily about the implementation rather than the behavior itself, would it be feasible to implement prefix matching using a dedicated helper function instead of using a trailing wildcard character like '*'?"
